GPT‑5, OpenAI’s most capable AI system yet, is now available worldwide in both Microsoft 365 Copilot and Copilot Studio. According to Microsoft commitment, they deliver the latest OpenAI models to Microsoft customers within 30 days of release—with enterprise-grade security, compliance, and privacy baked in.
How GPT-5 Enhances Copilot
-
- Dynamic Prompt Processing: Copilot now intelligently analyzes prompts and, thanks to GPT‑5’s real-time routing, selects the most suitable model to generate the best response.
- Speed with Simplicity: For straightforward queries, Copilot leans on GPT‑5’s optimized, high-throughput mode to deliver fast, clear answers.
- Deep Reasoning on Demand: For more complex or open-ended tasks, Copilot automatically switches to GPT‑5’s rigorous reasoning model—developing a plan, gathering context, and validating its responses before presenting them.
Mirroring Human Thought
Copilot’s dual-model design mirrors how humans tackle problems: quick responses for simple tasks and thoughtful analysis when complexity demands it.
Example use case:
-
- Ask Copilot to quickly summarize proposal responses—it’ll respond swiftly.
- Request help in evaluating and ranking those proposals—it’ll recognize the complexity, switch to the reasoning model, and provide a thoughtful, context-aware recommendation drawn from your documents, emails, meetings, and chats.
Availability
-
- Today: Microsoft 365 Copilot users with proper licenses can use GPT‑5 to better understand both web and work data. A “Try GPT‑5” button will appear in Copilot Chat—use it and get the GPT‑5 experience right away.
- Coming Soon: For users without a Copilot license, GPT‑5 is already rolling out and is expected to be fully available in the coming weeks.
- Copilot Studio Support: Starting now, developers can use GPT‑5 as the primary model in building custom Copilot agents to tackle complex business workflows.
